Saving Browser Changes

How do I save changes to themes? I've downloaded the Looking For Group theme and have manually changed both the default search engine and just a couple other options on the theme to get it the way I want it, but every time I close the window, my changes revert back. IS there a way to save these changes and if so, how?

1) The search bar stays the same (the one that shows up next to the address bar), but I've manually changed the search engine from Yahoo! to Google under the keyword.url config so that it would actually go through Google if I just put in a name in the address bar.

ie. If I just put 'hotmail' in the address bar, with Google it goes straight to the site whereas Yahoo! pulls up a full search on all possible websites.

However, this change always reverts back to Yahoo! when I close out the window.

2) The other option I've changed was the Looking For Group toolbar. This toolbar gives an extra web search box and a few other buttons for the Looking For Group site, but seeing as it's mostly extra stuff, I unselect it. However, just like the search engine change, whenever I close the window, it all reverts back.

3) New tabs always go to Yahoo! as well, so I set them to blank, and this gets reverted back when the window closes.

These are the main things I've tried to change and no matter what I do, it just won't save these changes and always reverts back to default once the window is closed.
